Scientists in southwest Germany develop erasable 3D printing ink for direct laser writing

“We’ve all heard the saying, “that’s why pencils have erasers,” but what if the same could be said for 3D printing? Beyond questions of making mistakes, principles of alteration, modification, and customization are essential to the world of manufacturing prototypes. Up until now, however, there’s never been a streamlined way to put these principles into practice. Altering an existing print has meant going back to the drawing board, and starting a new print from scratch. But that could all be about to change. Researchers at the Karlsruhe Institute of Technology (KIT) in southwestern Germany have developed an erasable 3D printing ink…”
